Columbia International Affairs Online (CIAO) is the most comprehensive source for theory and research in international affairs. It publishes a wide range of scholarship from 1991 onward that includes working papers from university research institutes, occasional papers series from NGOs, foundation-funded research projects, proceedings from conferences, books, journals and policy briefs.

The library’s online catalog contains information about the books, e-books, music scores, videos (both DVD and VHS), and sound recordings that the library owns. The catalog also contains detailed information about the print journal and magazine titles that the library owns, but it does not contain citations for individual articles.
